One blockage my husband had was when he ate an apple and forgot to peel it. He came home from work and we went to the ER. I had to call our physician for a referral to be admitted. He had the gall to ask 'why didn't he peel the apple'? I was so annoyed that I said 'that is not the time to question that' just have him admitted (glad we dropped his sorry ass soon after). My hubby was so close to being operated on, but the blockage cleared thank goodness.
